CFM: Cubic feet per minute; a unit of measure of air flow.
PSI: Pounds per square inch; a unit of measure of air pressure.
Cut-in pressure: While the motor is off, air tank pressure drops
as you continue to use your accessory. When the tank pressure
drops to factory set low pressure point, the motor will restart
automatically. The low pressure at which the motor automatically
restarts is called "cut-in" pressure.
Cut-out pressure: When an air compressor is turned on and
BASIC AIR COMPRESSOR COMPONENTS
The basic components of the air compressor are the electric
motor, pump, pressure switch and tank (see Fig. 1).
The electric motor (see A) powers the pump.
The pump (see B) compresses the air and discharges it into
the tank.
The tank (see C) stores the compressed air.
The pressure switch (see D) shuts down the motor when
the tank reaches a pre-set "cut-out" pressure. As compressed
air is used and the tank drops to a pre-set "cut-in" pressure, the
switch restarts the motor automatically, and the pump resumes
compressing air.
ASSEMBLING THE COMPRESSOR
This compressor was shipped with oil in the pump
crankcase. Check oil before operating the air
compressor, see Check Oil under Maintenance.
1. Unpack the air compressor. Inspect the unit for damage. If
the unit has been damaged in transit, contact the carrier
and complete a damage claim. Do this immediately
because there are time limitations to damage claims.
The carton should contain:
• air compressor
2. Check the compressor's serial label to ensure that you
have received the model ordered, and that it has the
required pressure rating for its intended use.
3. Locate the compressor according to the following
guidelines:
a. For optimum performance, locate the compressor close
to the power panel, as specified in ELECTRICAL
POWER REQUIREMENTS, and as close as possible to
the place where the air will be used. This ensures
maximum power to the compressor and maximum air
pressure to the tool. If both of these conditions
cannot be met, it is better to locate the compressor
close to the power panel, and use a longer air hose
or distribution line to reach the usage area.
b. The flywheel side of the compressor must be at least
12 inches (31 cm) from any wall or obstruction, in a
clean, well-ventilated area, to ensure sufficient air

GLOSSARY OF TERMS

• operator/parts manual
begins to run, air pressure in the air tank begins to build. It
builds to the factory set high pressure point before the motor
automatically shuts off, protecting your air tank from pressure
higher than its capacity. The high pressure at which the motor
shuts off is called "cut-out" pressure.
Well-ventilated: Means of providing fresh air in exchange for
dangerous exhaust or vapors.
Dedicated circuit: An electrical circuit reserved for the exclusive
use of the air compressor.

flow and cooling.
c. In cold climates, locate the compressor in a
heated building. This will reduce problems with
lubrication, motor starting and freezing of water
condensation.
d. Remove the compressor from the shipping pallet and
place it on the floor or a hard, level surface. The
compressor must be level to ensure proper
lubrication of the pump and good drainage of the
moisture in the tank.
CAUTION:
base for an operating compressor. Operating the
compressor while it is on the pallet will void your
warranty.
e. To prevent damage to
tank and pump, the
tank must be
shimmed so the
pump is level within
1/8" per lineal foot
maximum to distribute
oil properly. Fasten
to floor and NEVER
force tank feet to floor without shims when tightening.
We also recommend the use of vibration pads
(094-0137) under tank feet (F).
4. Connect an air hose or distirbution line (not included) to the
compressor.
